In this paper the most general bivariate distributions with second kind beta conditionals is fully characterized. This family is closed under inversions and the conditional moments are shown to be rational functions of the conditioned variable. Two subfamilies of dependent distributions is shown to have second kind beta marginals too. Finally, as a particular case, the most general bivariate distribution with second kind Pareto conditionals is characterized.  相似文献

The aim of this paper is to analyse the relationship between the diffusion process of social representations of justice by the press and their appropriation by readers. Two simultaneous cross-sectional studies were carried out. Study 1 analysed the meaning and the frequency of the word justice in the most important newspaper in Buenos Aires. The results indicate that the representation of justice has a retributive and institutional meaning. Study 2 investigated university students’ social representations of justice (N = 404) through a word association technique. The results showed that the central core of social representation has a retributive and institutional meaning, similar to the representations diffused by the most important newspaper. Nevertheless, significant differences were found with regard to the value attached to justice depending on the newspaper that the participants claimed to read. We can conclude that there is a mutual constitutive circular movement between the social representation of justice diffused by the newspapers and university students’ social representations. Moreover, the differences identified in the way justice was evaluated in the peripheral elements might express the existence of different positionings related to a hegemonic social representation.  相似文献

The authors present a psychometric study of the questionnaire proposed by the Gamblers Anonymous organization for the self-assessment of problem gambling. The study was carried out in Spain with two samples: one of 127 problem gamblers (mean age: 41.67; sex: 78.7% men; mean duration of the problem: 5 years) and the other of 142 social gamblers (mean age: 38.46; sex: 60% men). The questionnaire was self-applied, in the presence of one of the investigators in case any doubts arose. The results indicate that it is a good screening instrument, with high reliability (Cronbach's alpha = 0.94), good covergent validity (the correlation with the SOGS questionnaire is high (r = 0.94; p < 0.001)), good factorial validity (the questionnaire's structure is unidimensional and coherent (just one factor explains more than 50% of the variance)), and its discriminative power is high (diagnostic efficacy = 98.88%). The study offers a comparative analysis of this instrument with other measures of problem gambling, emphasizing its extraordinary performance.  相似文献

Current findings are still inconclusive with regard to the role played by the characteristics of social networks in INVs’ early geographical scope. This study analyses how entrepreneurial-oriented networks affect new ventures’ early geographical scope through critical capabilities. We have adopted a behavioural perspective to investigate the effect of social networks both on international new ventures’ geographical scope and on their critical capabilities such as absorptive and adaptive capabilities. Results from a sample of 183 Spanish international ventures confirm the importance of entrepreneurial orientation as a network characteristic for early geographical scope. Additionally, the positive effect of adaptive capability on new ventures’ early geographical dispersion has been confirmed but not so in the case of absorptive capabilities. Our results suggest that future research must be careful to assume international new ventures’ absorptive capability as a prerequisite to their cross-border expansion.  相似文献

This article contributes to recent overeducation literature on the impact of an initial education mismatch on workers’ future careers. Specifically, using the 2009 ad-hoc module of the Spanish Labour Force Survey, we quantify the differences in the probability of overeducation depending on the quality of individuals’ first match. To do this, we apply an extension of the recursive bivariate probit model, which allows potential endogeneity problems to be taken into account, as well as a dissimilar impact of the initial match for workers with different educational attainment. The results indicate that overeducation is a trap, since young workers who were mismatched in their first job are 40.2 percentage points more likely to be overeducated in a later one than those who were not. When decomposing this difference in two parts, one related to the pure effect of the initial mismatch and another one related to workers’ characteristics, we conclude that the pure effect is more important, and it depends on educational attainment.  相似文献

Literature researching the drivers of highly skilled migration (HSM) often prioritizes labor market returns to education and downscales the importance of public welfare. This article develops an innovative empirical strategy which allows us to see how a selection of pull factors attracts temporary and long-term educated migrants in Europe. To do so, we built a unique longitudinal contextual dataset merging information from the European Labor Force Survey (2000-2014) with selected Eurostat and OECD country indicators. Country-fixed effect time series allow us to concentrate on cross-country effects. Our evidence suggests that returns to education attract temporary HSM and long-term stayers equally. However, it is also shown that public welfare and taxation operate differently for these two groups and do not deter long-term residents. Our article proposes revisiting the assumption that HSMs are mere income maximizers. As we argue, long-term HSM may well be attracted by generous welfare setups.  相似文献

This paper analyzes the evolution of public policies on nuclear energy from an international perspective highlighting an interesting sociological paradox: the opposition to nuclear power contributed to the development of the environmental movement; and at present, the promoters of this kind of energy are including environmental arguments in their discourses, the fear of climate change and the reduction of CO2. Although the Kyoto Protocol does not accept this kind of energy as a clean development mechanism (CDM), its promotion is carried out on the basis of environment objectives, so that the nuclear lobby is obtaining more social acceptation thanks to the environmental discourse in the last four decades. For this research, the nuclear policies at an international level are analyzed inside a wider research about the nuclear debate financed by Encuentro Foundation (Spain).  相似文献

This project presents an analysis of the ergonomic conditions of three types of mattress and three types of pillow. The products are manufactured by a Colombian company which specializes in flexible polyurethane foam and other products designed for rest and relaxation. The project was developed through the University - Industry relationship: a strategic partnership based on the knowledge and strengths of each component. The conceptual theories that underpin the Ergonomics Research Division of the Design Studies Research Group (GED) provided the methodological approach for the project: the characteristics, the requirements and the relationships that are established between the components that constitute the User - Product - Context system (basic principles of the Ergonomics - Design relationship). An important factor in the project was the conception and measurement of comfort. Comfort can be measured on an objective level (quantitative measurement), and on a subjective level (a user's particular perceptions and tastes). What constitutes 'comfort' can vary from person to person, thus making the identification of criteria for the standardization of consumer products problematic. This project enabled design recommendations to be made to the Company vis-à-vis future proposals for mattress and pillow products. This experience of applied research was carried out by professors and students from the Faculty of Industrial Design at the UPB in Medellín, Colombia.  相似文献
